摘要： Multi-component mixed filament, wherein at least two spinning materials having poor affinity are mixed and dispersed in unitary filament in a nebular configuration containing at least 50 stars at least in one portion of the cross-section of the filament and the nebular configuration continues substantially in the longitudinal direction of the filament is manufactured by subjecting said spinning materials to at least eight times of "joining and dividing step in different phase" repeatedly to layer-multiply said spinning materials so as to form a nebular configuration in the cross-section of the resulting filament and then extruding the resulting mixture from orifice in a spinneret. In this manufacture, the preferable combinations of said two spinning materials having poor affinity are polyamide-polyester, polyamide-polyalkylne oxide, polyester-polyalkylene oxide and polyamide-polyolefin.

摘要： Conjugate filaments the components of which are comprised of the same constituents in dissimilar relative concentrations are produced by allowing the constituents of the molten stream of blended incompatible polymers partially to segregate in a forced flow conduit so that material removed from the outer periphery of the stream near the wall of the conduit will be of different relative concentration of constituents than material remaining near the center of the conduit and then removing separate streams of partially segregated material which are fed through suitable spinnerets to produce conjugate filaments. In another embodiment yarns the filaments of which are comprised of the same constituents in dissimilar relative concentrations are produced in the same manner.

摘要： An improvement in a continuous process for the relaxing heat treatment of crimpable filaments, particularly potentially crimpable filaments which comprises passing the filaments overfed from a filament charging apparatus through an ejecter, wherein a heated fluid is ejected, to subject the filaments to pre-heating and fiber separation, spraying a heated fluid onto the filaments at right angles from their circumference in a low tension zone under a tension as low as 1 mg/denier or less to subject the filaments to relaxing heat treatment, and then passing the treated filaments through a heat treatment chamber to subject the filaments to thermal setting, and an apparatus therefor.

摘要： CONJUGATE FILAMENTS OF POLYPROPYLENE ARE HEAT TREATED PRIOR TO DRAWING TO DEVELOP MAXIMUM CRIMPING POTENTIAL IN A REDUCED TIME. THE HEAT TREATMENT IS CARRIED OUT BY FOCUSING RADIENT HEATERS ON THE UNDRAWN YARN PACKAGE AS IT IS BEING WOUND. THE HEATERS ARE MAINTAINED AT A CONSTANT DISTANCE FROM THE YARN PACKAGE AND A TEMPERATURE OF 120 TO 200*C. IS MAINTAINED IN THE SPACE BETWEEN THE HEATERS AND THE YARN PACKAGE.
